AI trailer generator for movies that don't exist yet
The short answer
A trailer is the easiest movie to make with AI: 30 to 60 seconds of rising tension that never has to explain the ending. On StreamingWars, write a premise, pick a genre such as thriller or action, and ask for a trailer in your idea. The storyboard cuts it like one: a hook, quick escalating shots and a closing sting.

Why trailers suit AI shorts
Trailers are built from short, punchy shots, which is exactly how AI video films best. They promise a story instead of finishing it, so you get drama without needing two hours of plot. And they invite a sequel: if people want the movie, Watch more can turn the trailer into Part 1 of a series.
Cut it like a trailer
- 01
The calm, first 5 seconds
An ordinary world: a family dinner, a quiet office, a small-town diner.
- 02
The crack
One thing is wrong. A phone call, a stranger, a power cut.
- 03
The climb
Faster cuts, bigger stakes, one line of dialogue that sticks.
- 04
The sting
A last shot after the build-up: a reveal, a scream, a smile that shouldn't be there.
Write “a trailer for” at the start of your idea and the storyboard will cut it this way. Pick 30 seconds for a teaser, 60 for a full trailer.

Keep it original
Fan trailers for real films and famous characters aren't allowed. Invent your own movie, give it a title that sounds like a poster, and let the crowd decide whether they'd buy a ticket.
